What was the relevant law with firearms back in 85?
Was it legal for JB to use the .22 seeing on the premises ( for example such as rabbit shooting, target shooting, etc as though he had no girearm certificate and the gun was owned and certificated to use for Nevill Bamber.
I think NGB said he was on Neviles firearm certificate? Could be wrong though.
Lot of Ifs ILB, I don’t ever think we will know the truth, the sights wasn’t needed for close contact killing, maybe the silencer was needed, it keeps him further from his victims after all it has the name silencer, he could have used it and realised it was too long when he placed it on Sheila? So, like you said he could have got rid of it, or he could have wiped it clean (maybe there was more blood on it than we know of) and thinking it was clean put it in the box with the sights, it would look less suspicious than if it was on its own, if it was left out it would have been hard to say he went to shoot bunnies without it on?
Why go out after 12 hour shift to shoot a couple of bunnies at distance without a silencer on, if the silencer is useless why invent one in the first place?
He had no idea how the investigation would develop and it’s easy for us to say he would have done this or he would have done that, killers don’t think everything through or they would never get caught, so he had a choice ditch something the relatives knows is in the house or wipe it clean and give his story he left it he rifle minus the silencer? It nearly worked anyway, Taff and the investigation went for murder/suicide.
